Justification:
Listed as Critically Endangered because its Extent of Occurrence is less than 100km2 and its Area Of Occupancy is less than 10km2, all individuals are only known from a single location, and there has been a continuing decline in the extent and quality of its habitat, and in the number of mature individuals, in northern Puebla.

The disappearance of these permanent rivers has contributed to its decline, and perhaps extinction, and the damming of the Nexaca River for hydroelectric power, in particular, is believed to have affected this species.

The species is not known to occur in any protected areas. An extensive search within the known range of this species is needed to determine whether or not it still survives. It is listed as "Endangered" by the Mexican government.
